GOST engine is a reference implementation of the Russian GOST crypto
algorithms for OpenSSL. TLS clients using GOST engine when ciphersuite
TLS_GOSTR341112_256_WITH_KUZNYECHIK_CTR_OMAC is agreed and the server
uses 512 bit GOST secret keys are vulnerable to buffer overflow. GOST
engine version 3.0.1 contains a patch for this issue. Disabling ciphersuite
TLS_GOSTR341112_256_WITH_KUZNYECHIK_CTR_OMAC is a possible workaround.
